Liquid fertilizer

If I am using for instance a 10-10-10 liquid fertilizer.Is that the numbers for the concentrate itself or mixed with a gallon of water or other? Thanks for all your help

Most cannabis fertilizers are more on the order of 20-10-20.

Just seems like alot of the npk ratios
seem high in nitrogen during the flower phase…

That was just a number trying to find out the ratio

The highest nitrogen levels are required in early flowering when the development of foliage is experiencing its most torrid growth. Cannabis can double in size during the first few weeks of flowering.
